Getting a Foothold on Diabetic Foot Disease-Outcomes of a Multidisciplinary Clinical Pathway for Inpatient Diabetic Foot Care: A 17-Year Institutional Review.

INTRODUCTION: Diabetes foot disease (DFD) contributes to poor quality of life, clinical and economic burden. Multidisciplinary diabetes foot teams provide prompt access to specialist teams thereby improving limb salvage. We present a 17-year review of an inpatient multidisciplinary clinical care path (MCCP) for DFD in Singapore. METHODS: This was a retrospective cohort study of patients admitted for DFD and enrolled in our MCCP to a 1700-bed university hospital from 2005 to 2021. RESULTS: There were 9279 patients admitted with DFD with a mean of 545 (±119) admissions per year. The mean age was 64 (±13.3) years, 61% were Chinese, 18% Malay and 17% Indian. There was a higher proportion of Malay (18%) and Indian (17%) patients compared to the country's ethnic composition. A third of the patients had end stage renal disease and prior contralateral minor amputation. There was a reduction in inpatient major lower extremity amputation (LEA) from 18.2% in 2005 to 5.4% in 2021 (odds ratio 0.26, 95% confidence interval 0.16-0.40, P < .001) which was the lowest since pathway inception. Mean time from admission to first surgical intervention was 2.8 days and mean time from decision for revascularization to procedure was 4.8 days. The major-to-minor amputation rate reduced from 1.09 in 2005 to 0.18 in 2021, reflecting diabetic limb salvage efforts. Mean and median length of stay (LOS) for patients in the pathway was 8.2 (±14.9) and 5 (IQR = 3) days, respectively. There was a gradual trend of increase in the mean LOS from 2005 to 2021. Inpatient mortality and readmission rate was stable at 1% and 11%. CONCLUSION: Since the institution of a MCCP, there was a significant improvement in major LEA rate. An inpatient multidisciplinary diabetic foot care path helped to improve care for patients with DFD.

Biomechanical consequences of first metatarsaophalangeal joint arthrodesis on flexor digitorum longus function: A cadaveric study.

BACKGROUND: First metatarsophalangeal joint (MTPJ) arthrodesis is a common treatment modality for hallux rigidus with successful outcomes. However, the effect of arthrodesis on flexor digitorum longus (FDL) is poorly understood. The purpose of this study was to investigate this effect in a biomechanical model. METHODS: Ten cadaveric trans-knee amputated specimens were studied. Lesser toe range of motion (ROM) and FDL excursion on simulated FDL contraction were measured in the following three scenarios: (1) before 1st MTPJ arthrodesis, (2) after 1st MTPJ arthrodesis, and (3) after the knot of Henry release. RESULTS: 1st MTPJ arthrodesis reduced both mean lesser toe ROM and FDL excursion. However, there was improvement in these parameters after the knot of Henry release. CONCLUSIONS: FDL function was reduced following 1st MTPJ arthrodesis. This effect was contributed by soft tissue connections at the knot of Henry, where FDL crosses flexor hallucis longus (FHL). Therefore, with restriction of FHL movement after 1st MTPJ arthrodesis, FDL movement was also restricted. CLINICAL RELEVANCE: This result improved our understanding of 1st MTPJ arthrodesis biomechanics and suggested potential benefits of the knot of Henry release in 1st MTPJ arthrodesis to improve FDL function, thereby decreasing the rate of metatarsalgia and other associated problems.

Radial head and neck injuries in children with elbow dislocations: a report of three cases.

In children, traumatic elbow dislocations usually occur after the epiphysis has closed and with associated radial head and neck fractures and osteochondral fragments. The fragments are also usually interposed in the joint restricting complete congruent joint motion. We report on 3 children with traumatic elbow fracture-dislocation with associated radial head and neck injuries treated with open reduction and stabilisation. All patients achieved good outcomes and returned to pre-injury level of activities.
